no sata in device manager

Hey everyone. I am using windows 7 Rc1 7100 x86

hardware is asus a8n-sli motherboard which has a nforce4 sli chip set,
2x seagate hdd's
1 sata optical drive by LG

but anyway the problem I have is that windows 7 isn't showing any sata devices in the control panel (see attached picture)

while I was running vista I had downloaded and installed the correct drivers and didn't have a problem. I like win7 way more than vista so no going back.

I have done internet search for some drivers, found Fernandos_Vista&Win7_32bit_NF4-7_Test_Driverpack_v5.6 but they caused the machine to bosd. not helpful

I have also tried 15.23_nforce_winvista32_international_whql and had no luck what so ever.

so did see a couple of people say that win7 has built in drivers but if that's the case then why aren't these load

any help would be greatly appreciated

I have the same Issue. I have been led to believe that the last 3 entries you have there are the SATA controllers? I have exact what you have. There is settings in the BIOS relating to SATA. One id the AHCI setting which is related to SATA and the other is the SATA native mode. I use an EP45 DS3R GB board and I enabled the SATA native mode but NOT the AHCI mode. The last setting ya need to set before you install an OS. Again, this is what I have been told.

thanks for your help but that option I don't have in my bios. In fact I don't have AHCI anywhere in my BIOS

anyway I hadn't touched my computer bios in going from Vista (where it was working fine) to windows 7.

due to the age of the motherboard, there isn't any updates. it's an Asus A8N Sli motherboard running an amd 939 chipset. I need to upgrade but having some troubles finding the gear that I want for the price that I want to spend.

Anyway I did a couple of screen dumps from the manual (which looks just like the real thing) and here you have 1, the first page where it will list date/time etc. As it stands with my computer, the two HDD's that I have will be listed on the first and second sata controller and the dvd drive on the 3rd. If you go in to each of those options for the device you get number 2, The only two options for Exteneded Drive is None and Auto. If I set the HDD on Sata 1 to None then I can't boot up. INSERT SYSTEM DISK AND PRESS ANY TO CONTINUE message. For Access Mode the only options you have is Large and auto. but this changes the cylinder size etc and have nothing to do with the access mode.

So moving right along I go in to chipset settings (Where you would expect these settings to live) and you get to number 3,
I have disabled IDE channel 0 and 1. I don't have a need for them and really don't see why they should be turned on.
IDE DMA transfer access only options are Enabled/Disabled. With this disabled I can't boot.
SATA Port 1, 2 Enabled/Disabled, enables and disabled the deivce.
SATA DMA Access is Enabled/Disabled. I thought that this might have been it. DMA is like IDE access, but again with this disabled I can't boot.

I have done things like loaded the setup defaults and again this has made no change.

I am really starting to think that this is just down to the motherboard being to old for windows 7.

Oh I have no problems with running 7, in fact I'm not going to go back to Vista just because of this. I am going to be upgrading the hardware this year.

I am running 7 with only 2gb and 4gb page file and don't have any issues.

I would like faster access to my HDD, it's makes browsing all those thumbnails that much quicker. I would like to replace my hdd with SSD but hey dreams are free.
